According to the use, it can be divided into marks and numbers, indicative marks, warning marks, weight and volume marks and origin marks. Shipping marks and numbers, also known as shipping marks, are an identification mark.

According to the convention, the risk will not be transferred to the buyer before the commodity is specified. The most common and effective way of commodity specialization is to mark and number on the outer packaging of commodities.
